[Qemu-devel] [PATCH v4 00/10] Make qemu-img/qemu-nbd/qemu-io CLI more flexible |
Date: |

This series of patches expands the syntax of the qemu-img,
qemu-nbd and qemu-io commands to make them more flexible.
v0: https://lists.gnu.org/archive/html/qemu-devel/2015-10/msg04365.html
v1: https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg04014.html
v2: https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg04354.html
v3: https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg03381.html
First all three gain a --object parameter, which allows
instantiation of user creatable object types. The immediate
use case is to allow for creation of the 'secret' object
type to pass passwords for curl, iscsi and rbd drivers.
For qemu-nbd this will also be needed to create TLS
certificates for encryption support.
Then all three gain a '--image-opts' parameter which causes
the positional filenames to be interepreted as option strings
rather tha nplain filenames. This avoids the need to use the
JSON syntax, or to add custom CLI args for each block backend
option that exists. The immediate use case is to allow the
user to specify the ID of the 'secret' object they just created.
Finally, there are a few small cleanup patches
The first 4 patches in this series are a pre-requisite for
3 other series
- Support for TLS in NBD
- Support for secrets for passwd auth in curl, rbd, iscsi
(fixes a CVE issue in libvirt)
- Support for LUKS encryption passwords
Hopefully the --object patches are fairly uncontroversial
and can be merged soon. The latter patches for --image-opts
are very nice to have, but not a hard blocker right now
since the 'json:{....}' syntax can be used until they are
merged.
Changed in v4:
- Fix error reporting when object_create fails
Changed in v3:
- Rebase to resolve with conflicts against recently
merged code
- Remove use of errx()
Changed in v2:
- Share more common code in qom/object_interfaces.c to
avoid duplicating so much of 'object_create' in each
command
- Remove previously added '--source optstring' parameter
which replaced the positional filenames, in favour of
keeping the positional filenames but using a --image-opts
boolean arg to change their interpretation
- Added docs for --image-opts to qemu-img man page
- Use printf instead of echo -n in examples
- Line wrap help string based on user terminal width not
source code width
- Update qemu-nbd/qemu-io to use constants for options
- Update qemu-nbd to avoid overlapping option values
Daniel P. Berrange (10):
